Liebherr’s cold air systems only consist of a few components. They are not only of low weight, but also simple and inexpensive to service. In addition, the systems are characterized by very low operating costs and low energy consumption.

Originally, air cycle air conditioning technology was developed for the aerospace industry, where it has been used for more than four decades for air conditioning in aircraft. As one of the very first companies, Liebherr also began employing this technology in rail vehicle equipment. In 2002, Liebherr-Transportation Systems fitted a train of German operator Deutsche Bahn AG (DB) – an ICE 3 – with air cycle air conditioning systems for test runs. Additional fittings for the first model series as well as 13 eight-car trains of the second model series of the ICE 3 followed.

Environment-friendly and successful

Since then, the systems have proven extremely successful in DB's daily passenger transport operations. They are characterized, in particular, by their environmental friendliness, their robustness and their low operating costs. Furthermore, the energy consumption of air cycle air conditioning systems is extremely low compared with conventional systems. This has been verified, among other ways, through comparative measurements by DB.

The very successful results of the air cycle air conditioning systems are not only an affirmation for Liebherr-Transportation Systems, but also an incentive to work intensively on further developing air cycle technology and to make it usable for a wider spectrum of applications.

Liebherr-Transportation Systems have been selected by the rail vehicle manufacturer Bombardier Transportation GmbH of Mannheim (Germany) to develop and produce a compact and reliable cooling system for an innovative Li-Ion battery.

Bus with system PRIMOVE®

These batteries will be employed in the next generation of electric drive systems, which are set to power urban transit buses and light-rail vehicles in the future. The highly efficient cooling system will ensure that the battery runs under optimal thermal conditions. Prototypes of the system are being tested both at Liebherr's ultramodern test facilities and on demonstrator vehicles at Bombardier.

Liebherr battery cooling unit for road application

The Li-Ion battery is an integral component in Bombardier’s highly innovative inductive battery charging system PRIMOVE®. This system enables the main battery of the electric drive system to be recharged without contact to the trolley wires, so the vehicle does not have to interrupt its operation. The battery charging system will play a major role in reducing CO2 emissions in urban traffic.
